WILLIAM L. DODGE, OF EAST SOMERVILLE, MASSACHUSETTS.

GAGE FOR CUTTER-HEADS.

SPECIFICATION forming part of Letters Patent No. 269,025, dated December12, 1882. Application filed February 13, 1882. (No model.)

To all whom it may concern:

Be it known that 1, WILLIAM L. DODGE, of East Somerville, in the countyof Middlesex, of the State of Massachusetts, have invented a new anduseful Improvement in Mechanism for Manufacturing Moldings; and I dohereby declare the same to be described in the following specificationand represented in the accompanying drawings, of which- Figure l is avertical and transverse section, and Fig. 2 a horizontal and transversesection, of the cutters, cutter-heads, and their shaft of what isusually termed a variety molding machine, such heads and shaftbeingprovided with my invention. Fig. 3 is an edge view, and Fig. 4abottom view, of the cutter guards or fenders and their supporting-hub,to be described.

The improvement in question is not only for regulating the depth of cutof each cutter while it isin operation, but to prevent it from takingtoo deep or rank a cutinto the wood, and there by suddenly drivingagainst it (the said cutter) the hand of the attendant and inflictingthereon serious injury, such an accident having been met with by theundersigned while employed in making moldings by a machine of the kindabove mentioned.

The improvementconsists mainly in the com bination of an adjustableguard and a supporting device or devices therefor with each of thecutters and its supports and shaft, allbeing essentially as describedand represented.

In the drawings, A denotes the driving shaft or arbor of the cutters ofa machinefor sticking or forming moldings. B B are two cutters,'appliedto such shaft in the ordinary man-.

her-that is, by two disks or heads, 0 D, encompassing the shaft, andgrooved to receive the cutters at their opposite horizontal paralleledges, and held in place by a screw, a, and nut b, arranged as shown. Onthe shaft, and hetween the two cutters, is a hub, E, provided with aclamping-screw, c, to fix it to the shaft. It also has two wings or fiatprojections, (1,

extending from it, as shown. Upon each of the said wings and againsteach of the cutters, at its upper edge, is a flat fender or guard, G,which has in it at its inner end a curved notch, e, to receive theshaft. The outer end of this guard is curved, as shown at i, to the arcof a circle havingaradius whose center is in or about in the axis of thehub. Each of the guards is fastened to the sustaining-wings by aset-screw,f, that goes through a slot, g, in the wing and screws intothe guard, all being as shown. The guards, when arranged with its curvedbearing-edgei and the cutting-edge ofthecutter, to which the saidguardis applied, a notch, k, the object of which is to prevent sliversor fibers of the wood from becoming caught audjammed between the guardand the cutter, so as to interfere with the proper operation of thelatter. A stick or molding-blank, while being reduced by the cutters, ismaintained by the guards in its proper relations to the said cutters,and cannot be caught by either of them so as to he suddenly drawn inwardin a manner to bring against a cutter the hand of an attendant who mayhave hold of such stick. The guard is arranged at the upper part only ofeach cutter, and does not extend down along the entire cuttingedge ofthe said cutter, the shavings being thereby free to escape withouthinderance from the guards.

. I claim- In combination with the molding-machine cutters, theirsupporting-heads and drivingshaft, the adjustable guards, and theirsustaining winged hub, adapted to the said shaft and cutters,substantially and for the purposes as set forth.
